RFD 1171: The presence loop, and every role in it
Problem
RFD 1166 ranked twelve models against each other and never says what any of them is for, so a reader cannot tell which stage is missing. Ranking stages of one pipeline against each other was the error.
Decision
One loop, four movements, and each runs both ways:
forward inverse
make a description -> a body fit a picture -> the body
dress a layer onto the body recover the body out from under
be it a person supplies motion friend a model supplies itEach inverse is under-determined, which is why every one has a checker and why Kimodo sits beside rf-detr rather than behind it.
The See-Through taxonomy is the vocabulary. VALID_BODY_PARTS_V3 names 23 parts, nine worn and the rest body, and that line is the try-on axis. A try-on is then masking treated as corruption: remove topwear and LaMa fills the hole the garment leaves.
The boundary is subtraction, not segmentation. The posed ANNY mesh gives the body outline through silhouette.py; MoGe depth gives the person’s outline and the camera both project through. What lies between is worn — no taxonomy-aware segmenter, so no labelled corpus. contour.py makes either a fixed ring. DETAILS.md places every candidate and names the empty stages.
